Radon Fan Replacement in Longmont, CO

Get an existing radon system pulling again.

Signs Your Radon Fan Has Failed

A radon fan runs around the clock and typically lasts about 5 to 10 years. When it fails, the system stops protecting your home, and nothing inside the house will tell you.

Check the U-tube manometer on the vent pipe. If the liquid on both sides is level, the fan isn't pulling. A fan that has gotten loud, a rattling pipe or a tripped alarm usually means the same thing.

We replace failed fans, fix leaking or blocked pipe, and check the whole system so you know it's working again. Call (720) 790-3231.
